Interpreter: 3.1.1

Start -> Run -> cmd: cd %locatie% unde %locatie% este locul unde se afla PortScanner.py ce contine codul de mai sus. Cititi usage.

Un scanner de ip-uri : port-uri simplu si rapid. Are functia de a scana liste cu ip-uri sau port-uri dar si raze de ip-uri / port-uri in moduri combinate. Avertizare acustica prin difuzorul intern al UC.

Nu are rost sa mai pun credite ca cca. 90% din ce este pe forum in Python este scris de mine byte cu byte, oricum mereu cand ceva e facut in totalitate de mine adaug un "[cmiN]".

Respect si ms.. (oricum eu mi`am rezolvat de ieri problema). + rep se merita

root:RHEL5 [~]# python PortScanner.py

File "PortScanner.py", line 48

except Exception as message:

^

Ceva nu`i bine..

[cmiN]

Foloseste Python 3.1.1, in versiunile 2.x ar fi trebuit sa scriu "except Exception, message" dar in 3.x syntaxa arata asa: "except Exception as message".
